Almon Strowger

Almon Brown Strowger (March 10, 1839 – April 12, 1902) was an American inventor and businessman who fundamentally transformed telecommunications through his invention of the automatic telephone exchange. Born in Penfield, New York, Strowger initially worked as an undertaker in Kansas City, Missouri. The story goes that he became motivated to develop the automatic exchange after discovering that calls to his business were being intercepted by a competitor's wife who was a telephone operator. His breakthrough invention, the Strowger switch or step-by-step switch, was patented in 1891 and allowed telephone calls to be routed automatically without human operators. This innovation was revolutionary for the telecommunications industry, dramatically improving call routing efficiency and reducing operational costs. The Strowger switch became the standard technology used in telephone exchanges throughout the 20th century, and variations of his design remained in use for decades. Strowger founded the Automatic Electric Company in 1901 to manufacture his invention, establishing a company that became a major player in the telecommunications equipment industry. His invention laid the groundwork for modern automated telecommunications systems and is considered one of the most important technological advances in communication history.
